Application ie March 16, 1914. Serial No. 824,977,

To all whom it may concern.' Be it known that l, 'VINFRED T. RYAN, a

.citizen of the United States, residing at `Vandergrift, in they county of Westmoreland and State of Pennsylvania, have invented a newand useful. Shear-Table, of which the following is a specification.

My .invention relates to apparatus used in conjunction with vmetal cutting shears employed to sever multiple-length sheet and tin bars and similar materials into short pieces in handling the sheared materials and in supporting the rear end of the multiple length pieces of the materials being sheared.

One object of'my invention is to provide a shear receiving table of novel'construction having improved means for transfer-- ring anddeliveringshort pieces of the ma.- terials being'- sheared between the shear knives into position to `be cut by the shears,

'fand for supporting such materials during the shearing operations. Y

Another object ofthe' invention is to provide Va shear receiving table having novel means whereby the vend of a multiple length blank projecting beyond the shear knives is' yieldingly supported while moving into position yto be cutand during the lshearing- Aoperatnon.

A further-object; of this'iinvention Vis to provide a shear receiving table having novel y means for supporting the materials to be sheared and for moving the sheared mate rials. after the shearing operations, from in front of the knives of the shear.

Still further objects of my invention will appear hereinafter as the invention is more fully described and claimed.

Referring to the drawings forming partv of this specifica-tion, Figure 1i is aside elevation showing a bar shear havinga shear table constructed and applied for usetherewith in accordance with my invention. Fig. 2 is an end elevation of the apparatus illus! trated in'Fig. 1 and Fig. 3 is a sectional plan taken on the line lll-Hl of Fig. 2. Fig. 4 is a side elevation showing a modified form of shear table as constructed and arranged and applied for use inconnection with a shear in accordance with my invention, and Fig. 5 is a plan of' the apparatus shown in Fig. 4.

` ln the accompanying drawings, in which like parts have similar numerals applied thereto, the numeral 2 designates a shear having a stationary bottom shear knife and a power driven vertically reciprocating` top knife 4 between which lthe materials to be severed are delivered lengthwise into engagement with the shear stop or gage 5 located in front of the shear. The gage 5 is suspended-`from or mounted upon a horizontallyextending' arm 6, being adjustable thereon toward and away from the shear knives to vary' the length into which the severed materials are cut by the shear.

t the rear ofthe shear Q is a feed table 7 having a' series of' positively driven feed rollers 8`upon or by which the materials to of materials to be cut arefedbetween the shear knives 3 and 4 into engagement with the shear gage 5. The pinch 'roller is mounted in vertically movable bearings 310, 10, above the end roller S which is positively drivenby the line shaft ofthe feed table inthe usual known manner.

paratus shownin Figszand 5, a receiving roller table is employed having at leastone positivelydriven roller, this roller table bev ing' located on the front side of the shear, between the shearknives and the shear gage ln the apparatus shown by Figs. l, 2' and 3, and also in the modified form of ape .5 in position to engage with' and feed, as

well as assist the pinch rollers in feeding, materials to be cut into engagement with the shear stop or gage.

Referring now to the construction shown l 1n Figs. 1, 2 and 3 of the drawings, it will v be: seen that the receiving tableA comprises two feed rollers 11 and 12 mounted in bearings 13. The bearings 13 are secured to the upper ends of the forked members forming the sides 14 of the table, and the lower end of the sides 14 are pivotally connected by the shaft 1 5 to one end of the rocking arms 1'6 which are keyed or otherwise secured to the rock shaft '17. ...A guide 18 between the sides 1li of the table projects into the open- (,)n one end ot" the sha'tt is a. sprocket wheel connected by the sprocket chain 51 with the sprocket wheel 55 on the pivot shaft 15, and also mounted on this shaft is a second sprocket wheel 56, which is connected to and rotated by the wheel 5 The wheel 513 is connected by the sprocket chain 57 to the sprocket wheel 5S on one end of the shaft for the roller 12 so that when the shear drivingmechanism is actuated the feed roller 12 is positively rotated. Keyed 0 or otherwise fastened to one end ot' the rock shaft 17 is a swii'iginp; arm or lever 5t) by which the shaft 17 Iis actuated in moving the rollers 1l and 19. into and outotl their raised position (shown dotted in Fig'. 1). The

5 lower end ot the. arm 59. is connected by the reach rod (SO to the pivoted operating` lever (i1. A counterhalance lever GL) on the shat't 17, having" a,1 counterweight (i3 thereon, is

also provided to lessen the torce necessary' 30 in manually operatingr the lever (31 to raise and lower the rollers 11 and 12. In the apparatus of Figs. 1, 2 and i. a horizontally reciprocating table or carrier 22 is also used. this table beine' mounted on slides 23, 2-, on 5 the top of the stands 2v-l, to receive the materials as sheared and transfer the sheared materials sidewise from in llront o1 the shear knives nd discharge such materials upon -the car 25 located at one side ot the shear 2 and. the rollers 11 and 12 formingr the re,- ceivingf table. The table or carrier 22 and the car 25 upon which the cut materials are stacked in piles in the operation oi the cai'- rier. and by which the piled materials are z)ftaken away from the shear, forms suhject matter of Patent No. 1.129.211, tor a har piler, issued February 23, 1915, to llo 'ard G. h'l'cllvried. and no claim tol this apparatus is made herein.

1n the modified t'orm o'l apparatus shown in Figs. l and 5, the receivingl table eolnprises a series oi three positively driven leed rollers 2U, 27 and '28, these rollers having shafts ext-endingr into the bearings toi-med in the sides 2f). 29, ot the receiving table. av-ne end ot' the shafts tor the rollers projects through the hearings in the side 29 of the table and has a spur lQear il() thereon. The gears 30 are operatively connected together by the idler spur pinions 31 and the shaft 32 for the roller iti is provided with a sprocket wheel through which the series ofy rollers 2G, 27 and 2S are positively driven. The shaft projects through its hearings in thel sides of the receiving tablcinto the bearinfrs 34 on one end of the nivoted arms 35 and the opposite end of t-he sides of the roller tahle engage with the follower plate 3G for the helical springs 37 which extend between the arms 35 to yieldingly support the pivoted tahl'e at one end on the arms. The sin-ings 37 are secured upon the pivoted arms 35 by means of the bolts 38. Extending tl'irough the hearing 39 onethe base ot the shear 2 is a horizontal pivot shat't 40 on which the lever arms 35 are pivotally mounted, these arms beingr keyed to the shaft 10 so as to he rocked thereby. One end of the shaft l0 projects through the deadseye bearing); l1 which is positioned at one side of the shear, and a lever l2 having' a handle on its upper end by which the `roller table is tilted or rocked manually is fastened to the end ot' the sha-ft 1t). The shat't Jr() is also provided with a counterweieht lever arm 13 havingT a counterweight -l-lwhich is adjustably mounted thereon to counterlnilance and hold the receivingr roller table in its raised or lifted position, (shown hy full lines in Fig. 5) to receive and support materials caused to project between the shear knives ot the shear. Stops l5 are provided ou one end ot the pivoted lever arms 35 to limit. hy engagement with the base ot the shear 2, the downward swinging movement ot the arms 35. Positioned at the discharge end ot' the receivingr table is an in clined chute lo which receives the sheared materials delivered thereto by the table and on which the sheared mateI 'ials slide to the bottom thereof in position ytfo he removed to the. heating` tui-nace or other place in which the sheared materials are used. The end 'feed roller H on the delivery table 7 is provided with a sprocket wheel +7 which is connected by a sprocket chain -lS with :t sprocket wheel -lfl loosely mounted on the pivot sha tt. and 'formed integrally with the sprocket wheel 4") is a sprocket wheel 50 which is connected bv the sprocket chain 51 with the sproclv'et wheel 321 on one end of the shal't Il l'or the roller iti ot' the tilting receiving` table. so that when the sprocket wheel t7 rotates with the feed roller H ot the delivery table 7 the roller 2G and, through the connecting;` spur e'ears 21() and B1.y the` rollers` 27 and 2H ot the tilting' receiving4 table, are positively rotated.

It will he. readily understood that any numher ot' bars that can be ted 'forwardly `between the shear knives can he cut simultaneously` the numher being limited by the width ol the shear knives and relative width o'll the materials beinfl cut.

The operation ot the apparatus shown in ities. l. 2 and 33 will nowhe descrihed.

The lonar pieces ot the materials to hesevcred are transferred lengthwise, upon lthe rollers 8 ot the delivery table 7 to the shear 2, and after cropping the front end of the j the sheared materials from in 't1-ont of thel Liedes; f ra,

materials, the cut end thereof is moved into eneidrement with the shear gage .5. rThis gage willv have heen adjusted and fixed on the arm (3 upon which it is ad'justahly mounted at the required distance. from the shear knifves to sever pieces oi the desired length from ,the multiple length materials. llarh time a relative approach ot the shear knives is eliected the reeiproeatingl' table :'22, which is operatively connected to the. shear operating' mechanism, will move lengthwise Vlimwardl)v and hack so as to first transfer shear. and in its backward movement, dischai-ee the materials therefrom. ln feeding; the materials hetween the shear knives preparatory to cutting pieces therefrom, the pi m-h rollers formed hy the positively driven and roller H of the delivery tahle and the roller lo which operates in conjunction therewith, grip and assist in the lengthwise armement ot the materials, especially after the multiple length materials, through sue-w ressive cuttings; operations. are reduced to a comparatively short length. When successive. cutting;r operations have reduced the length of the materials heine: sheared to less than the distance between the shear stop 5 'A and the end 'roller 8 of thedelivery table 7 the materials projecting hetweenthe shear knives'will rest upon the shear tahle, in such case the rollers 3.1 and l2 heine lifted into the raised position shown hy dot-ted lines in Fig. l, by means of the manually operated hand lever 61. As the rollers 11 and 12 are positively driven through the sprocket cha-ins 5l, 57,v and sprocket wheels and 55, 56 and 58, the. shox. t pieces of materials are positively fed forwardly against the shear 5 and are held out of engagement with the hottom shear knife 3 and the top of the re ciprocatinf.;q trhle during such forward movement. After the short pieces of mateY rial are moved into engagement with the shear sagre the shra r is actuated to cause the upper --hear knife 4 to descend andrutsuch pieces to'lenle'th, The hand lever (il is then actuated to lower these eut materials upon the reciprocatingr tahle Q2. and, through the eonnertingr mechanism, the reciprocating tahle 22 is caused to move first forwardly and then lhackwardly. so as to first shift the Iposition ot' the materials resting on this tahle from in front ot the shear knives, andv then discharge and deliver the eut materials therefrom upon the car 25, or other means for reeeivingr the materials at the discharge end o' thi` reciprocating tahle 22. above descrita-sd operations are then repeated with successive. multiple length materials hv ine' sheared in the operation of the appa ratus of Figs. 1, 2 and j In the operation of the apparatus shown in Figs. Lt and 5 the multiple length materials to he sheared are moved lengthwise by The the rollers S, 8, of the delirerv table 7 until the forward end 'of the materials to he cut project slightly bevond the shear knives. The crop end is then cut oli the materials and the rollers ot the delivery tahle 7 are rotated to advance. the forward end-of the materials heine cut into engagement with the shear gaee 5. The shear knife le is then caused to approach the kni'lfe 3 so as to sever the part ot' the materials projecting' between the shear knives from the halance thereof which is supported on the rollers t oi the deliver)v tahle. ils the shear knives approach each other the severed,material is caused to rest upon the rollers 26, 2T, and 2S, forming' the receiving' tahle. rllhe lever arm l2 is then rocked manually, which tilts the rollers of the receiiinglj table from the position shown hy full lines into that shown hy dotted vlines in Fig. l. At the same time the rollers 8, t, of the delivery-table on the rear of the shear are caused to again rotate and feed forwardly the material heine sheared until the front end thereof is again projecting between the shear knives and in engagement with the gage The rotat|on of lthe feed roller 8 through the sprocket chain 48 causes the sproeketwheels l) and 50 to-rotate and. through the sproeln-ft chain 51 and sprocket wheel 33 `on the shaft 32A For the. roller 2G, matarte this roller. The spur gears 3G, 3l connecting,T the rollers 27 and 28 with the roller 56 cause these rollers to he rotated,and in 'this way'the shear-ed materials are delivered 'from the receiving: table into the upperend of the inclined chute' lo in which the materials slide to the lower end thereotl in position to removed. When hy successive cutting' operations the length of the materials heine: sheared is reduced to a. length than the distance hetween the end roller S the deiivery roller table 7 and the shear gage the gnrrieetiny,h end oli materials oit' this' length rests upon the rollers 2G, 57, 2S. ot the feed or shear table, and the rotation of these rollers causes such short length materhds to he fed forwardly into eneasement with the shear gage. The upper shear knife is then caused to descend to eut such remainingl portion oit the materials into -pieees ofthe desired length, a short piece `toi-ming a rear crop end usually remaining. rllhe above described operations a re then repeated withsiuzcessive tin hars or series of tin hars in cutting' the multiple length hars into hars ol the desired length with the appfratus of Figs. '-t and 5.

The advantages of my invention will he apjiarent to those skilled in the art. By the use of my improved reeeirin table the materials to he cut are easily and quieklymoved into position. for cutting; from in front of the shear wheneut. The apparatus is simgfe and is easily kept in repair.
